So anyway, when the satellite’s orbit degrades further and further, making to closer to earth and experience more atmospheric drag, at some point earth’s gravity field will overpower the satellite and pull it onto the earth, and the satellite will fall.

Not just man made satellites, but moon, earth, they all will eventually fall. They are just more stable than our own small satellites. I mean, the earth has been in a stable orbit for 4 billion years now. Now, it will eventually fall. But don’t worry. In another 5 billion years, the sun would enter its red giant phase, and expand out to meet earth, and evaporate the whole thing.

But anyway, you made me think about something. Perhaps, in the future, we might find aliens who are specialized in recycling glass bottles. If comparative advantage works at the interstellar level too, we should totally outsource the aliens to recycle our glass bottles. Something to remember when I make my own universe.

As a monument to the stars, I suggest dumping all our garbage to the outer-space, so that empty Coca Cola bottles may become monuments (for a while, until they get sucked into a black hole or fall into a star, or recycled by aliens).
